Abstract
The evolution of the amorphous phase in the solid state reaction of alloys with composition Fe67Ti33 was followed with neutron and X-ray scattering techniques in the case of metal powders treated by mechanical milling (MM) and by mechanical alloying (MA). The X-ray and neutron diffraction data show that the milling time is related to the coordinate of reaction. In the case of neutron small-angle scattering, data analysis of the log I vs. log Q graphs suggests that the fractal concept is useful in describing the earliest stages of the solid state amorphization reaction.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
